Abstract A novel method for the determination of cobalt (II) by stripping voltammetry is
described. It involves an adsorptive accumulation of the cobalt (II)-2-aminocyclopentene-1-
dithiocarboxylic acid complex on a hanging mercury drop electrode, followed by a stripping
voltammetric measurement of the catalytic reduction current of the complex at–1.4 V at pH=
9 (vs. Ag/AgCl). The effects of various experimental parameters on the catalytic current were
investigated. An accumulation time of 60 s results in a low experimental limit of detection ...
